2 Claims.

This invention has reference to rotary brushes and one object is to provide means whereby brushes of this nature may be manufactured with greater rapidity than heretofore.

Another object of the invention is to provide a rotary brush of such a substantial construction that it may be operated at a much greater speed.

A further object of the invention is to provide face plates for a rotary brush so formed that it will be impossible for relative movement between the plates and their brush segments.

Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings in which:

Figure l is an elevational view of a rotary brush formed in accordance with my invention,

Figure 2 is a transverse sectional View thereof,

Figure 3 is a detail sectional view of a male face plate,

Figure 4 is a similar view of a female face plate,

Figure 5 is an edge View thereof,

Figure 6 is a transverse sectional View of Figure 5, and

Figure 7 is a detail sectional View of Figure l.

In the drawings and specification like reference characters indicate like parts and in which il), is a brush formed according to my invention and which comprises a male face plate l i, and a female face plate iE. The plate ii, is provided with a pressed in central portion it, having an arbor opening ifi, in the center thereof. The rim portion i5, of this plate is provided with a series of equi-distant struck out tongues it and t6', the purpose of which will presently be explained. The walls i5 and i?, are parallel with one another and the joining Wall Il, has struck' therefrom a series of equally spaced tongues I9. The female plate l2, is provided with a central opening 2i?, the diameter of which is equal to that of the struck in portion i3, of plate i l, and its outside diameter is the same as that of plate il. The plate i2, is provided with a series of equally spaced struck out tongues 2l, and between these tongues are'provided equally spaced slots 22. Y

In assembling the parts of the device the circular brush 23, is placed between the-plates il and l2, and then put under pressure, causing the tongues i5, to penetrate the body 2li, of the brush bristles and projectthrough slots 22, in member l2, and pressed down at right angles to securely bind members II and I2, together. At

the saine time lugs 2 i, of the plate l2, penetrate the member 52e, only and rest upon the inner face 2E, of the rim i5, of member Ii. The same operation turns the tongues iS, out upon the inclined wall it, and into engagement with the inner face it, of member i2, thus the brush is completed.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size and rearrangement of details and parts such as come within the purview of the invention claimed may be resorted to, in actual practice, if desired.

Having now described my invention that which I claim as new and desire to procure by Letters Patent is:

l. A rotary brush comprising a hub disk having a centrally disposed arbor receiving opening therein,V a bristle clamping flange concentric with the periphery of the hub disk, said flange being offset to one side of the general plane of the hub disk, radially spaced tongues struck from the disk at its junction with the ange, said tongues being bent back upon themselves to form an annular row of supporting lugs concentric about the central opening in the disk, an annular row of bristle tufts radially disposed on the face of the flange facing the hub, a clamping ring supported on the lugs in concentric relation with the flange for clamping the bristle tufts against the flange, said ring having an annular row of radially spaced openings therein and ring clamping tongues struck from the flange and projecting through the openings in the ring, the free ends of said tongues being clinched over the outer face of the clamping ring to clamp the bristle tufts in place.

A rotary brush comprising a hub disk having a centrally disposed arbor receiving opening therein, a bristle clamping ange concentric with the periphery of the hub disk, said flange being offset to one side of the general plane of its iunction with the nange, said tongues being bent back upon themselves to form an annular row of supporting lugs concentric about the central opening in the disk, an annular row of bristle tufts radially disposed on the face of the flange facing' the hub, a clamping ring supported on the lugs in concentric relation with the flange for clamping the bristle tufts against the flange, said ring having an annular row of radially Y 3 4 spaced openings therein, ring clamping tongues struck from the flange and projecting through REFERENCES CITED the openings in the ring, the free ends of said The following references are of record in the tongues being clinched over the outer face of le of this patent: the clamping ring to clamp the bristle tufts in 5 UNITED STATES PATENTS place, and an annular row of spacing tongues struck from the clamping ring'and extending Number Name Date inwardly through the bristle tufts to engage the 1,566,313 Cornell Dec. 22, 1925 ange and hold the flange and ring in spaced 1,631,998' Carman et al.
